Exceder LED3 low frequency sounders and sounder strobes

Eaton designed the Wheelock Exceder LED3 low frequency sounder strobes (LFHSK3/LFHSH3) and sounders (LFHNK3) to meet dual sleeping room codes - NFPA 72 for fire alarm and NFPA 720 for Carbon Monoxide (CO) alarm in a single device. The low frequency sounders and sounder  strobes can replace a facility’s existing appliances, utilizing the same single pair of wires that are currently installed, offering a simple retrofit to meet new codes for sleeping rooms.

Meets NFPA 72’s 20 ms light pulse duration requirements
